Polyurethane – PU
Pneumatic tubes made of polyurethane, PU tubes for short, are the first choice when pneumatic controls are to be connected. They are available in numerous sizes and are characterized by their flexibility and small bending radii. PU pneumatic tubes are available in many different colors, which is useful when connecting complex controllers to keep track of the individual lines. They meet numerous requirements because they have different special properties, such as protection against welding spatter, flame retardant or electrically conductive.
Polyamide – PA
Compared to PU tubes, pneumatic tubes made of polyamide, or PA tubes for short, are more temperature and pressure resistant. As a result, the tube material is stronger and therefore less flexible – polyamide is semi-rigid and kink-resistant. As a rule, PA tubes are completely pressure-resistant at a temperature of -50 °C to +20 °C (then falling as the temperature rises) and are therefore ideal for use as compressed air lines and compressed air brake lines.
Polyethylene – PE
Pneumatic tubes made of polyethylene, or PE tubes for short, are very light, impact-resistant and largely resistant to acids, alkalis and salt solutions. PE tubes are suitable for use in a temperature range from -30 °C to +80 °C and are the most cost-effective option among pneumatic tubes.
PTFE / PTFA / PFA
PTFE / PTFA / PFA pneumatic tubes are suitable for working in extreme temperature ranges from -20 °C to +150 °C. They fit all common connector types and are available as standard in natural colors and as a CS type in green and red. PFA tubes can also be welded.
